Abstract: MINE SHAFT LINER        ABSTRACT OF THE DISCLOSURE            In the mining of minerals from the earth, it is necessary to drill deep bore holes typically between 3000 and 6000 feet in the earth.  In order to protect those entering the hole for additional mining operations, after drilling the hole, the hole is lined with a stack of specially constructed lining segments.  These segments are formed of either prestressed concrete or steel.  The segments are lowered one at a time into the bore hole so as to build up a stack within the hole, thereby lining the hole.  The segments are carried to the hole on a transporter and then lowered by the transporter into the hole.  Guide cables are threaded through guide conduits provid-ed within the segments so as to maintain the orientation of such segments during the operation.  The weight of the segment as it is lowered is supported by fluid, normally the drilling mud, that fills the hole and the transporter until the segment comes into contact with the top of the uppermost segment on the stack of those segments already placed into the hole.  Grout is then placed between the lining segments and the inner wall of the bore hole.  The grouting process is periodically carried out after every few segments have been placed into the hole.  After the lining operation has been completed, the miners can enter the bore hole for other mining operations.

Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus for providing an audible representation of any data which can be represented in a format of M x N individual datum.  Each datum can have individually specified properties.  One application of this technique is to provide an audible representation of a visual scene.  Since these data can readily be assimilated by the brain, they can provide either an aid to the visually handicapped or supplementary information to the normally sighted.  A matrix of M x N pixels is generated in which distance along one spatial axis is represented by discrete sound frequencies and distance along the orthogonal axis is represented by the time lapse following a reference sound pulse.  The light intensity of a pixel is represented by the amplitude of the sound at both a particular frequency and a particular time after the reference sound pulse is generated.

Abstract: -23-ELECTRICAL SWITCH ASSEMBLY AND METHOD OF MANUFACTURE ABSTRACT OF THE DISCLOSURE The present invention provides low cost electrical switch assemblies and methods for manufacturing same. The switch assembly comprises an array of resiliently flexible metallic conductors arranged in predetermined circuit pathways on a dielectric carrier panel. A plurality of apertures or cavities are provided at predetermined locations in the carrier panel. The switch contacts comprise a pair of generally L-shaped fingers which are integral extensions of the flexible conductors. The fingers extend from opposite edge surfaces of the carrier panel defining an associated aperture or cavity, to pass one another over or within their associated aperture or cavity, with the free ends of the fingers terminating adjacent one another. The free ends of the L-shaped fingers extend in part above or below the plane of the carrier panel, and are positioned in spaced relationship to one another so that the conductors they connect are normally open, but are sufficiently close to one another so that slight deflection of the fingers from their normal orientation moves the free ends in contact with each other to thereby close the switch. Alternatively, the free ends of the L-shaped fingers are positioned in contact with one another so that slight deflection of the fingers from their normal orientation breaks their contact. The metallic conductors and integral switch contacts may be formed by photoimaging and either chemical milling or additive techniques such as plating up or solder doming, and/or mechanical milling and/or precision die stamping techniques.

Abstract: ABSTRACT OF THE DISCLOSURE         A capacitive pressure transducer is disclosed in which a sensing diaphragm bearing an electrode is mounted to flex in response to applied fluid pressure relative to a reference member having an opposed electrode.  A thin film or layer of dielectric material such as glass covers the reference member electrode and has formed therein a concavity matching the flexed curvature of the sensing diaphragm at its limit position.        The dielectric layer has a high compressive strength and substantially enhances linearity by providing a substantially higher capacitance than the equivalent fluid-filled space.  The transducer is retained within a transducer assembly under compressive preload, the assembly further including thermal strain relief means.          Also disclosed are methods of making the transducer, which methods include thick film screen deposition techniques for forming concavities having preselected contours in the dielectric layer.

Abstract: ABSTRACT OF THE DISCLOSURE         A device is provided herein for dosing or for pumping a liquid or slurry in a controlled manner.  The device has a piston freely recipro-cating in a cylinder.  Members are connected to the cylinder on the opposite sides of the path of the piston movement for feeding the liquid or slurry under pressure into the cylinder in order to move the piston or for discharging liquid or slurry from the cylinder by means of the pres-sure of the liquid or slurry directed into the cylinder to the opposite side of the piston, when the piston returns.  A valve is disposed in each of the feed and discharge members of the liquid or slurry for their alter-nate opening and closing.  Switches are fitted at the ends of the cylinder for sensing the position of the piston.  Finally a control unit is provided for controlling the stroke frequency of the piston, and thereby the volume flow of the liquid or slurry, and for transmitting the signal given by the switch to the valve member in order to open and close it at different positions of the piston.  According to the invention, the con-trol unit is fitted to adjust the time interval between the starts of the piston movement.  Thus the stroke frequency of the piston and the volume flow of the liquid or slurry remain constant in spite of variations in the feed pressure and viscosity of the liquid or slurry.
